Add a small wrapper around libzfs_core's lzc_send_space() to libzfs so
that every legacy ZFS_IOC_SEND consumer, along with their userland
counterpart estimate_ioctl(), can leverage ZFS_IOC_SEND_SPACE to
request send space estimation.
The legacy functionality in zfs_ioc_send() is left untouched for
compatibility purposes.

In any pool without the extensible dataset feature flag already enabled,
creating a dataset with dedup set to use one of the new checksums would result
in the following panic as soon as any data was added:

Inspection showed that feature->fi_feature was 7, which is the value of
SPA_FEATURE_EXTENSIBLE_DATASET in the spa_feature enum.
Testing shows that the panic can be prevented by explicitly setting extensible
dataset as a dependency for the sha512, edonr, and skein feature flags.
Alternatively, the new checksums code could possibly be changed to obviate the
need for the dependency.

commit log from upstream:
Fix race in parallel mount's thread dispatching algorithm
Strategy of parallel mount is as follows.
1) Initial thread dispatching is to select sets of mount points that
don't have dependencies on other sets, hence threads can/should run
lock-less and shouldn't race with other threads for other sets. Each
thread dispatched corresponds to top level directory which may or may
not have datasets to be mounted on sub directories.
2) Subsequent recursive thread dispatching for each thread from 1)
is to mount datasets for each set of mount points. The mount points
within each set have dependencies (i.e. child directories), so child
directories are processed only after parent directory completes.
The problem is that the initial thread dispatching in
zfs_foreach_mountpoint() can be multi-threaded when it needs to be
single-threaded, and this puts threads under race condition. This race
appeared as mount/unmount issues on ZoL for ZoL having different
timing regarding mount(2) execution due to fork(2)/exec(2) of mount(8).
`zfs unmount -a` which expects proper mount order can't unmount if the
mounts were reordered by the race condition.
There are currently two known patterns of input list `handles` in
`zfs_foreach_mountpoint(..,handles,..)` which cause the race condition.
1) #8833 case where input is `/a /a /a/b` after sorting.
The problem is that libzfs_path_contains() can't correctly handle an
input list with two same top level directories.
There is a race between two POSIX threads A and B,
* ThreadA for "/a" for test1 and "/a/b"
* ThreadB for "/a" for test0/a
and in case of #8833, ThreadA won the race. Two threads were created
because "/a" wasn't considered as `"/a" contains "/a"`.
2) #8450 case where input is `/ /var/data /var/data/test` after sorting.
The problem is that libzfs_path_contains() can't correctly handle an
input list containing "/".
There is a race between two POSIX threads A and B,
* ThreadA for "/" and "/var/data/test"
* ThreadB for "/var/data"
and in case of #8450, ThreadA won the race. Two threads were created
because "/var/data" wasn't considered as `"/" contains "/var/data"`.
In other words, if there is (at least one) "/" in the input list,
the initial thread dispatching must be single-threaded since every
directory is a child of "/", meaning they all directly or indirectly
depend on "/".
In both cases, the first non_descendant_idx() call fails to correctly
determine "path1-contains-path2", and as a result the initial thread
dispatching creates another thread when it needs to be single-threaded.
Fix a conditional in libzfs_path_contains() to consider above two.

zfs_main: fix `zfs userspace` squashing unresolved entries
The `zfs userspace` squashes all entries with unresolved numeric
values into a single output entry due to the comparsion always
made by the string name which is empty in case of unresolved IDs.
Fix this by falling to a numerical comparison when either one
of string values is not found. This then compares any numerical
values after all with a name resolved.

stdin is closed and ncat initiates a graceful shutdown of the SCTP
association. This is not expected by the client. Therefore, the
ncat-based discard server is replaced by a perl-based one.
In addition, to remove the dependency from ncat, which needs to be
installed via the nmap port, also the code testing for a free SCTP port
is changed to use the perl-based client.
Finally, remove some debug output from the report generated.
